EVALUATION OF SPECIFIC PROPERTIES OF FINISHED WOOL AND WOOL-BLENDED POLYESTER WOVEN FABRICS

Abstract

This article presents experimental evaluations of 5 samples of finished woven wool and wool-blend polyester fabrics with different proportions of raw materials provided by Nam Dinh Silk Textile Joint Stock Company for research. Experimental evaluations are sequently performed with fabric capillarity determined according to TCVN 5073-90 standard, the wrinkle resistance degree of fabric determined according to TCVN 7425:2004 standard, the breathability of fabric determined according to TCVN 5092:2009 standard, the shrinkage of fabric after washing determined according to TCVN 8041:2009 ISO 5077:2007 standards. The research results prove that the material composition of the fabric affects some fabric properties, specifically concerning fabric sample PLE1 (LE (P/W/C 29.5/70/0.5) has the ability to the highest capillarity in the longitudinal and transverse directions of 0.83 cm/min and 0.93 cm/min, respectively; PLE2 fabric sample has the largest crease return angle in the longitudinal direction reaching 174.5° with anti-creasing coefficient is 96.4%; fabric sample PLE3 has the best air permeability at 53.3 cm3/s/cm2. fabric sample LE has the highest shrinkage in the longitudinal direction at 1.8%; fabric sample PLE3 has the highest shrinkage; the horizontal direction reaches 4.0%. The research results can provide suggestions for textile product designers to choose appropriate materials when designing to meet usage requirements, contributing to improving product quality textile products.
